JS interop via webcomponents is "the way" (vs ports). Re JSON decoding, agreed, and we cover in the episode: it's a solved/solvable problem that isn't popularized via a nice package...yet. But I think you've zero'd in on the pragmatic pain points; webcomponents is the revelation that was missing in the communication on the migration from 18 to 19, unfortunately.
